How Was Antarctica Before The Ice at Nicole Alarcon blog

How Was Antarctica Before The Ice. Scientists have produced the most accurate portrait yet of what lies beneath antarctica's ice sheet. Like alaska's mighty yukon, a broad river once flowed across antarctica, following a gentle valley shaped by tectonic forces at a time before the continent became encased in ice. With more ice, there was more reflection of sunlight back to space (a higher albedo) and this acted to further cool the surface temperature of the continent. Understanding when glaciers first wove their way across antarctica will help scientists better model the ice sheet's response to earth's climate shifts, the researchers said. Like alaska's mighty yukon, a broad river once flowed across antarctica, following a gentle valley shaped by tectonic forces at a time. The ice of antarctica is not a smooth sheet but continuously changing thanks to high winds and glaciers inching across the continent,. Many studies hint that antarctica’s ice sheet began to form about 34 million years ago (sn: Once ice on antarctica began to spread, the process reinforced itself through positive feedback mechanisms. 12), but where that ice sheet originated and how it evolved have long been.
